Hi Avanti,
OpenCDISC validator was designed as a desktop application. It is a platform independent and requires only Java. UNIX is OK! We are aware of some companies which installed and run it on servers. However support for such solutions is quite limited.
OpenCDISC Enterprise edition is a commercial web-based server application for corporate clients. See http://www.pinnacle21.net/ for details.
Kind Regards,
Sergiy
